Why wouldn’t the AF just turn it over to the Army? Gets it out of their garage, and the infantry still has the CAS they need? Just common sense, isn’t it? (I have no military background.)
(IIRC/IIUC) It's not even an act of congress, but a Memorandum of Understanding from 1952.
We wouldn't be having these problems if we didn't have the unconstitutional Air Force (this is to say that there's nothing authorizing an Air Force
in the Constitution, only an Army and Navy). — It seems to me that having an Air Force is dangerous to military effectiveness because politicians (and a surprising number of modern military/DoD thinkers) don't really seem to understand the need for boots-on-the-ground as the basis of controlling an area.
As a result of the above, we're setting ourselves up for being Russia in Afghanistan those decades ago where, as one Russian general said something like: During the day we controlled hundreds of kilometers, during the night two blocks from our position.
